Workflow Java Deferred Agent Listener is getting to "System Deactivated" status after sometime. It started happening suddenly in Production from last 3 days. Details from the page is below:

Name Workflow Java Deferred Agent Listener

Inbound AgentWorkflow Java Deferred In Queue

InformationThis Automatic Service Component has been restarted the maximum of 10 times after stopping with error. Thus, it has been system deactivated -> oracle.apps.fnd.cp.gsc.ProcessorException: Error occurred while dequeueing -> oracle.apps.fnd.wf.bes.QueueHandlerException: Could not execute() the CallableStatement or retrieve OUT parameter -> java.sql.SQLRecoverableException: No more data to read from socket

I tried following steps - How to Manually Process the Events from Workflow Queues When The Deferred Agent Listener Won't Start (Doc ID 953103.1)

Note: I have changed the file path from the alert log extract as I dont want to disclose the information to public. Another ML Note that I referred is : Ora 600 [Ktuabt-1] reported In 11gR2 (Doc ID 1372715.1). I have not set the event mentioned in the note. I want to learn what caused it and what does the event do.
